Description

Overview Description: 
   Another situation where rows are not repainted in a <tree>.
   
   Just cataloguing this one separately, to avoid confusing the other 
   various bugs that apply to trees, etc.

1) Create a new profile (just so you have no prior persisted information
   about which folder should be open)

2) Go to ftp://ftp.mozilla.org/pub/mozilla/

3) Open these top-level folders:
      brownbag
      contrib
      l10n
      libraries
      nightly

4) Ensure that the browser content area is short enough vertically that 
   a scrollbar is now showing (e.g. the distance between 'brownbag' and 
   'nightly' is greater than the height of the viewport).

5) Click to put the selection on 'nightly'

6) Arrow down to move the selection down 10 subfolders. This should cause 
   a scroll to occur as the view tracks the selection

7) Arrow up to return the selection to 'nightly'

8) Arrow left on 'nightly' to collapse the nightly folder

Actual results:
   When you press the left arrow, the top 8 or 9 rows of the screen 
   (subfolders of 'brownbag') will not be repainted. (However, if you
   force a paint, they do reflect the correct contents, and the scrollbar
   is not out of synch. This situation is fully recoverable, and is not
   a crash situation, to my knowledge.).

Expected results
   Er, those rows should be painted. (stating the obvious).

Reproducibility: 100% in this build.

Build Date & Platform Bug Found: 
  win2k debug trunk build plus hyatt's patch from bug 57139
   (trunk build pulled 11:30pm Friday Oct 27th night)
   (Note: no assertions occurred in the debug build for this 
   steps to reproduce.).

Note: I couldn't seem to find an analogous situation is mailnews or
the bookmark manager.

By the way, you can reproduce this when using the mouse, instead of arrow keys.
The key is to open the nightly folder, move the view down, then collapse the
nightly folder again.

jrgm, is this fixed by the patch in 57139?

No, this was in a build that included that patch for bug 57139. 

(In the current candidate build on win2k, doing these steps -- the result is 
a much, much worse situation -- the top 8 or 9 rows, and the bottom 8 or 9 rows
are blank, not just unpainted (they are dead rows). The behaviour with this 
patch is much better than the current behaviour (and really isn't a new bug, 
it's just something that needs future love)).
